" Are the days of CRTs over? "
Probably yes !
I have two old crt monitors rigged up in the workshop and would not swap them for a flat screen.
In the house,we have four lcd screens connected to computers,seven if you count the flat screen tv's capable of running a pc on them.
Though im not one for worrying about adjusting the brightness/contrast etc...i do find the crt's more robust.
I think the main reason for the flat screens is space saving and the look nice feel factor.
